Business news for Mon, 31 Dec 2007 & with word buyout. 3 news.

When I sat down for my annual review of what I've written over the past year, something jumped out at me. Usually, I write about widely diversified subjects. But in 2007, I devoted an inordinate number of columns to the shenanigans of leveraged buyout firms and the attempts by the world's central banks to rescue financial markets.

LONDON (MarketWatch) -- The Financial Services Authority is probing a jump in the share price of U.K. waste services group Biffa ahead of an announcement in November that it had received a 1.2 billion pound ($2.4 billion) takeover bid, according to a report in the Times (of London) newspaper. The report said the FSA has written to various parties involved in the talks to ask what they knew about any possible bid before buyout groups HgCapital and Montagu Private Equity revealed their offer. The inquiry is a part of a continuing focus at the regulator on insider trading ahead of major announcements, the newspaper added.
